Hi, on a cluster running 0.94.1 , both ssd osds of 1 host are repeatedly marked down:

2015-06-29 15:26:18.806731 7f8a22aaf700 0 -- 10.143.16.2:6802/1755 >> 10.143.16.1:6800/1685 pipe(0x3f892000 sd=24 :44531 s=2 pgs=1718 cs=1 l=0 c=0x3f86b9c0).fault with nothing to send, going to standby

I see that on both osds.

I rebooted the affected host, but the problem remains.. after a few minutes they are marked down again.
I don't see any other problems on the host..
nothing special to see in dmesg too.

What could be the problem here?
